I Have No Mouth And I Must Scream - Mephiles has no mouth and must scream

He screams, nay, weeps, for he knows, as much as we all do, that his villainy can only be known in one of the worst games ever created, and he must live that torment, again and again, having to create overly complicated plots, having to die continuously as Solaris… as long as Sonic 06 is still played to this very day.

he was a great villain in concept but was poorly used.
